Enhanced non-classical electrostriction in strained tetragonal ceria [PDF]

Nature Communications
Electrostriction is the upsurge of strain under an electric field in any dielectric material. Oxygen-defective metal oxides, such as acceptor-doped ceria, exhibit high electrostriction 10-17 m2V-2 values, which can be further enhanced via interface ...

Data-driven methods for discovery of next-generation electrostrictive materials

npj Computational Materials, 2022
All dielectrics exhibit electrostriction, i.e., display a quadratic strain response to an electric field compared to the linear strain dependence of piezoelectrics.

Lead-free Zr-doped ceria ceramics with low permittivity displaying giant electrostriction [PDF]

Nature Communications, 2023
Electrostrictors, materials developing mechanical strain proportional to the square of the applied electric field, present many advantages for mechanical actuation as they convert electrical energy into mechanical, but not vice versa.

Ultra-high electrostriction and ferroelectricity in poly (vinylidene fluoride) by ‘printing of charge’ throughout the film [PDF]

Nature Communications
Electrostriction is an important electro-mechanical property in poly (vinylidene fluoride) (PVDF) films, which describes the proportional relation between the electro-stimulated deformation and the square of the electric field.
